[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution for a vacuum insulated transport box for cold chain transportation: A vacuum insulated transport box for cold chain transportation includes a box body 1, a box cover 2 hinged to the top of the box body 1, a handle 4 provided on the box cover 2, and a groove provided on the box cover 2 for easy placement of the handle 4. The handle 4 is hinged in the groove, making it easy to flip out when in use and flip back into the groove when not in use, without affecting the stacking between the two box bodies 1. The box body 1 and the box cover 2 are made of impact-resistant polycarbonate material, giving the transport box elastic deformation capability. When subjected to impact, the polycarbonate material can absorb external force energy through molecular chain stretching and twisting, preventing the box body 1 from breaking directly. One side of the box body 1 and the box cover 2 are connected by a hinge, and the other side is fixed by a metal buckle. A sealing strip is provided on the box cover 2. When the box cover 2 is closed on the box body 1, the storage cavity 5 is in a sealed state.

The positioning component includes a limiting slot 3 installed at the four corners of the top of the lid 2 and a positioning post 31 at the four corners of the bottom of the container 1. The size of the positioning post 31 is compatible with the size of the limiting slot 3, and the positioning post 31 can be inserted into the limiting slot 3 to realize the stacking of two containers 1. During cold chain transportation, multiple containers 1 can be stacked using the positioning component. When two containers 1 are stacked, the positioning post 31 at the bottom of the upper container 1 will be inserted into the limiting slot 3 at the top of the lower container 1 to realize the stacking positioning of the two containers 1.

[0024] The interior of the box 1 has a storage cavity 5, and a vacuum chamber 8 is formed on the inner wall of the box 1. The vacuum chamber 8 can form a vacuum insulation layer on the inner wall of the box 1, while the filling chamber 7 can form a cold chain layer on the inner wall of the box 1. A vacuum extraction port 12 is also provided on the front side of the box 1. One end of the vacuum extraction port 12 is connected to the inside of the vacuum chamber 8, and a valve is provided on the other end of the vacuum extraction port 12.

The inner wall of the vacuum chamber 8 and the inner side of the box cover 2 are provided with a heat insulation film 21. The heat insulation film 21 is an aluminum foil reflective film, which can further reduce radiative heat transfer and improve the heat preservation performance.

[0025] The inner wall of the box 1 is also provided with a filling chamber 7 between the storage chamber 5 and the vacuum chamber 8. The filling chamber 7 can be filled with freezing materials such as ice cubes, crushed ice, dry ice, liquid nitrogen, and liquid helium to ensure the temperature inside the storage chamber 5 during cold chain transportation. The top of the box 1 is provided with a sealing plate 6 for sealing the top of the filling chamber 7 and the vacuum chamber 8. The sealing plate 6 is made of metal and has sealing strips on its bottom and sides. The top of the box 1 is provided with a groove for easy insertion of the sealing plate 6. The sealing plate 6 is fixed in the groove with bolts. After the sealing plate 6 is fixed, it can completely seal the vacuum chamber 8 and the filling chamber 7.

[0026] The storage cavity 5 is equipped with a temperature and humidity sensor 51 and a vibration sensor 52. A digital display 11 is installed on the front side of the housing 1, and a battery box 13 is installed at the bottom of the housing 1. The battery box 13 contains a rechargeable battery. The temperature and humidity sensor 51, the vibration sensor 52 and the digital display 11 are electrically connected. The rechargeable battery can be connected to the digital display 11 and the sensors through wires. The wires can pass through the vacuum chamber 8 and the packing chamber 7, and the perforation points are sealed to ensure the effectiveness of the vacuuming. The temperature and humidity sensor 51 and the vibration sensor 52 can monitor the temperature and humidity inside the storage cavity 5 in real time, and can also monitor the vibration of the housing 1. The monitored data can be displayed on the digital display 11.

[0027] In summary, this utility model designs a cold chain transport box that combines a vacuum insulation layer and a temperature monitoring system. By using high vacuum to isolate heat conduction, it significantly improves insulation efficiency and reduces energy consumption. Moreover, the box body 1 is equipped with a temperature control system, which is suitable for extreme environments of around -300℃. At the same time, the integrated outer polycarbonate material can ensure the safe transport of goods.
